How Many Bundles of Shingles in a Square? Counts by Brand
By Marko VisicBSc Physics, University of Ljubljana
Shingles are sold by the bundle and estimated by the square, so the count that matters is bundles per square.
Three bundles make one square for most asphalt shingles, 3-tab and architectural alike, and a roofing square is 100 sq ft of roof. Many laminated shingles cover 98.4 sq ft per three bundles, about 32.8 sq ft a bundle. Heavier designer shingles come four or five bundles to the square.

Bundles per square by brand
The counts below are from each maker’s spec sheet. The standard laminated lines from GAF, Owens Corning and CertainTeed all pack a square into three bundles; they differ in how many shingles that takes and in how much roof the three bundles actually cover.
| Shingle | Type | Bundles per square | Shingles per square | Coverage per square | Coverage per bundle |
|---|---|---|---|---|---|
| GAF Timberline HDZ | Laminated | 3 | 64 | 98.4 sq ft* | 32.8 sq ft |
| Owens Corning Duration | Laminated | 3 | 64 | 98.4 sq ft | 32.8 sq ft |
| CertainTeed Landmark | Laminated | 3 | 65 | 98.4 sq ft | 32.8 sq ft |
| CertainTeed Landmark PRO | Laminated | 3 | 66 | 100 sq ft | 33.3 sq ft |
| GAF Royal Sovereign | 3-tab | 3 | 79 | 98.8 sq ft* | 32.9 sq ft |
| Owens Corning Duration MAX | Laminated | 4 | 64 | 98.4 sq ft | 24.6 sq ft |
| Owens Corning Berkshire | Designer | 5 | 45 | 99.5 sq ft | 19.9 sq ft |
GAF puts the general rule plainly: three bundles per square for most standard asphalt shingles, with up to five for some specialty shingles because of their weight. Its own Woodland line comes four bundles and 56 shingles to the square, and Owens Corning’s heavier Duration MAX packs the same 64 shingles as Duration into 4 bundles.
How many shingles in a bundle
A bundle of standard laminated shingles holds 21.3 on average. Owens Corning specifies not less than 20 in each Duration bundle and 64 in three; CertainTeed Landmark comes 65 to the square, about 21.7 a bundle.
Smaller 3-tabs pack more: GAF’s 12-by-36-inch Royal Sovereign runs about 79 to a square, about 26.3 a bundle. Heavier shingles come in smaller bundles: 16 for Duration MAX, 14 for GAF Woodland and 9 for the 18¾-by-38-inch Berkshire.
How many square feet in a bundle of shingles
Divide the square’s rated coverage by its bundles. Duration and Landmark rate three bundles at 98.4 sq ft, which is 32.8 sq ft a bundle; Timberline HDZ works out the same from its size, 13¼ by 39⅜ inches at a 5⅝-inch exposure. Landmark PRO’s 100 sq ft square gives 33.3 sq ft, Duration MAX’s four bundles 24.6 sq ft each and Berkshire’s five 19.9 sq ft.
IKO prints the figure per bundle: 33.3 sq ft for Cambridge and Dynasty, 25 sq ft for Crowne Slate and 20 sq ft for Armourshake. Its Marathon Plus AR 3-tab covers 32.3 sq ft a bundle, so a square takes three bundles plus two shingles.
Why 98.4 sq ft matters when you order
Take a roof with 3,000 sq ft of surface. Counting three bundles per 100 sq ft gives 90 bundles of Duration; at 32.8 sq ft a bundle the same roof takes 92, before any waste. GAF says contractors usually add 10–15% for waste, which brings the order to 101 to 106 bundles.
The coverage is on the wrapper: every bundle is marked with the area it covers and how many make a square, so check it before you order by bundle count alone.
What is a roofing square?
A roofing square is 100 square feet of roof surface, a 10-by-10-foot patch measured along the slope. A square of shingles is the bundles sold to cover one: three for most lines, four or five for heavy ones.
How to calculate roofing squares
Add the area of every roof plane and divide by 100. If you only know the house, multiply its footprint out to the eaves by the pitch multiplier first. A 40 by 30-foot house with 1-foot overhangs covers 1,344 sq ft; at a 6/12 pitch the multiplier is 1.118, so the roof is 1,502.6 sq ft, or 15.03 squares.
The roof square footage calculator does this for gable, hip and shed roofs, and the roof pitch chart lists the multiplier for every pitch.
3-tab and architectural shingles
Both come three bundles to the square. The piece count differs because each shingle shows a different area to the weather. A 12-by-36-inch 3-tab laid 5 inches to the weather shows 180 square inches, so a square takes about 79. A 39⅜-inch laminated shingle at 5⅝ inches shows 221 square inches, so 64 do the same job.
Royal Sovereign also comes in that metric size, 13¼ by 39⅜ inches, so check which one the store stocks before matching a repair.
How many bundles on a pallet?
Each maker sets its own pallet count, so it changes by product. IKO publishes its numbers: 56 bundles of Cambridge, Dynasty, Nordic or Marathon Plus AR, 52 of Royal Estate, 60 of Crowne Slate and 36 of Armourshake.
At three bundles to the square, a 56-bundle pallet is 18.7 squares. Armourshake’s 36 bundles at 20 sq ft each cover 720 sq ft, about seven squares.
Shingle bundles FAQ
How many square feet does a bundle of shingles cover?
About 33 square feet in a three-bundle square: 32.8 sq ft for laminated lines rated at 98.4 sq ft per square, such as Owens Corning Duration and CertainTeed Landmark, and 33.3 sq ft for a full 100 sq ft square. Four-bundle shingles cover about 24.6 sq ft a bundle and five-bundle ones about 19.9 sq ft. The wrapper states the coverage.
How many square feet in a square of shingles?
A roofing square is 100 square feet of roof, and a square of shingles is the bundles sold to cover one. Many laminated lines rate those bundles at 98.4 sq ft, so a 3,000 sq ft roof takes 92 bundles rather than 90, before waste.
How many architectural shingles in a bundle?
About 21. Owens Corning packs not less than 20 into each Duration bundle and 64 into three; GAF Timberline HDZ also comes 64 to the three-bundle square, and CertainTeed Landmark 65.
How many bundles in a pallet of shingles?
It depends on the product. IKO stacks 56 bundles of its Cambridge, Dynasty, Nordic and Marathon Plus AR shingles on a pallet, 52 of Royal Estate, 60 of Crowne Slate and 36 of Armourshake. For another brand, the supplier’s listing for that shingle gives its count.
Sources & method
Bundle and shingle counts are as each maker publishes them for one square. Coverage per bundle is the rated coverage per square divided by bundles per square; where GAF gives shingles but no coverage, coverage is shingles × length × exposure ÷ 144 square inches. The order example divides roof area by coverage per bundle and rounds up, with the waste added to the area first.
